EB Green is what I've used for years.
"EB Green is found throughout the Navy and rumored to originate from the Electric Boat shipyard, hence the name. If you’re a US Submariner (current or former) you probably heard stories about and experienced the unbelievable strength of “EB Green” duct tape. This stuff is
not your Home Depot run of the mill duct tape; I swear when applied properly its just short of epoxy backed Kevlar....."
